Researchers Raise Cloned Rhesus Monkey to Adulthood

In a groundbreaking scientific feat, researchers in China have successfully raised a cloned rhesus monkey to adulthood. This marks the first time such an accomplishment has been achieved with primates, and it has the potential to revolutionize medical research. However, the ethical implications of this breakthrough raise complex questions that demand careful consideration.

The Experiment and its Success:

The research team, led by Dr. Qi Zhou of the Chinese Academy of Sciences Institute of Neuroscience, utilized a modified version of somatic cell nuclear transfer (SCNT) – the same technique that produced Dolly the sheep in 1996. The modified technique involved replacing the nucleus of an egg cell with the nucleus of a skin cell from an adult female rhesus monkey. This reprogrammed egg cell was then implanted into a surrogate mother monkey, who successfully gave birth to a healthy male clone named Zhong Zhong.

Zhong Zhong has since thrived, reaching full sexual maturity and even fathering offspring of his own. This demonstrates the viability and safety of the modified SCNT technique in primates. The researchers published their findings in the prestigious journal Nature Communications, sparking widespread scientific interest and debate.

Potential Applications in Medical Research:

The successful cloning of Zhong Zhong opens up a plethora of possibilities for medical research. Rhesus monkeys share a significant portion of their DNA with humans, making them ideal models for studying various human diseases. By creating genetically identical populations of cloned monkeys, researchers can conduct more precise and controlled experiments on conditions such as Alzheimer’s disease, Parkinson’s disease, and cancer.

This could lead to faster development of new drugs and therapies, ultimately benefiting human health. Additionally, cloned monkeys could be used for organ transplantation research, potentially alleviating the critical shortage of donor organs.

Ethical Concerns and the Slippery Slope:

Despite the potential benefits, the ethical implications of primate cloning are undeniable. Concerns have been raised about the welfare of the cloned monkeys, who may experience psychological distress due to their artificial origin and potential confinement in research facilities. Furthermore, the success with primates raises the specter of human cloning, which is widely condemned on ethical and moral grounds.

The slippery slope argument suggests that if primate cloning is deemed acceptable, public resistance to human cloning could weaken, leading to unforeseen and potentially dangerous consequences. Moreover, the potential for commercialization of cloning technology raises concerns about exploitation and discrimination.

The Road Ahead:

The successful cloning of Zhong Zhong represents a significant scientific milestone, but it also necessitates a thorough ethical discourse. Open and transparent discussions involving scientists, ethicists, policymakers, and the public are crucial to ensure that this technology is used responsibly and for the greater good of humanity. Striking a balance between scientific progress and ethical considerations will be essential in navigating the uncharted territory of primate cloning.


The successful cloning of a rhesus monkey to adulthood is a testament to human ingenuity and scientific advancement. However, it is imperative to remember that scientific progress should not come at the cost of ethical principles. As we move forward, we must carefully consider the potential consequences of this technology and strive to use it in a way that benefits both science and society as a whole.
